I was going to suggest the connection between Antarctica and Dacres Wood Nature Reserve, which was one of Shackleton's first expedition according to Steve Grindlay. Unfortunately Antarctica is not yet an Olympic nation.

It is a strange list that includes a connection to Germany due to a statue in Edinburgh for James Clark Maxwell, whose work was 'a big influence on the German-born physicist Albert Einstein'. They also include Bletchley Park in the list of sites with a connection to Germany, having broken their enigma codes there in the 1940s.
